• Primary Identifier: Expr13662
• Pattern: unc-39 reporters were expressed by muscles and multiple neurons during embryonic development and into the adulthood. Notably, robust expression of unc-39 reporters was observed in the embryonic RID precursor, embryonic RID, and newly hatched L1 larvae. Post-embryonically, unc-39 expression was selectively decreased in some neurons, including RID.

	The C. elegans life stage spanning 620-800min(hatch) after first cleavage at 20 Centigrade. Cell number remains at ~560 cells, with some new cells generated and some cells go through programmed cell death. A stage after elongation is over. The last stage of embryogenesis. Also called pre-hatched embryo, late embryo or morphogenetic embryo.		fully-elongated embryo Ce	WBls:0000021
